Proud to have worked on the zkAPI protocol design and the cryptography implementation that backs it … and more broadly to have collaborated with the OpenAnonymity team within EF / dAI 🙂↕️
Congrats @kenziyuliu @mingyech @DavideCrapis 🔥

Quick updates on the Open Anonymity project (@OpenAnonProject)!
1. OA-chat is live! You can now signup: chat.openanonymity.ai
2. We collaborated with @ethereumfndn (@VitalikButerin, @DavideCrapis, @VittoStack, @curryrasul) to develop zkAPI, a new zero-knowledge protocol for accessing gated / paid APIs with unlinkability. It’s like a generalization of OA unlinkable inference that also abstracts payments away. Now also available on OA-chat!
I'm excited because more infrastructure should exist where privacy and sovereignty is foundational and people are in control.
1/ Built a CLI/TUI app — consilium 🧠
Multiple AI models work together as a "consilium" to produce a better answer than any single model alone

2/ Under the hood — NSED coordination protocol: N models independently answer, then each evaluates all responses blindly. Scores aggregated via quadratic voting — two moderate votes outweigh one extreme. The cycle repeats until convergence.

1./ Now when announcement is finally out, maybe I'll make a short explainer. 🧵
You don’t have this in US? 👀
🇨🇳 I found the rentable powerbanks in China
One scan to pay with Alipay and then you take the battery and you return it later
This would never work in US or Europe because people would just steal the powerbanks
Readers added context they thought people might want to know
Rentable power banks have been available in Europe and the US for several years.

🫡 more updates soon
@curryrasul just shipped the first PoC implementation of vOPRF-ID for generating secure nullifiers from Web2 identities — includes zk circuits, a registry contract, and testing infra.

OPRFs are one of the most widely used privacy tools, but they’re under threat from developments in quantum chips.
In this work we present Leap, a lattice-based OPRF using MPC tools (OT, OLE) for post-quantum security—fast eval (<1ms) & efficient PSI.
Joint work with @isec_tugraz, Trento, and AIT. To appear at @IACReurocrypt 2025.

New post on EthResear.ch!
Web2 Nullifiers using vOPRF
By:
- curryrasul
- levs57
🔗 ethresear.ch/t/21762
Highlights:
- vOPRF (verifiable Oblivious PseudoRandom Functions) can generate unique identifiers (nullifiers) for Web2 identities without revealing personal data.
- This method allows for anonymous voting and airdrops, where users can prove their identity without exposing their actual email or username.
- The protocol involves multiple parties, including the user, an OPRF server, and a smart contract platform like Ethereum.
- Using nullifiers helps prevent users from being tracked across different applications, enhancing privacy.
- The approach can be applied to various Web2 to Web3 transitions, making it versatile for different privacy-focused projects.
ELI5:
This research discusses a new way to create anonymous identities for users on Web2 platforms using a method called vOPRF. It allows users to prove their identity without revealing personal information, enabling secure and private interactions like voting or claiming rewards.
1/ I wrote down my thoughts about vOPRF/MPC-based approach vs @Rarimo_protocol's approach for Web2 ID "nullifiers".
Read it here: curryrasul.com/blog/thoughts…
I compare these approaches and review advantages and disadvantages of both; and most importantly I propose a new solution ->
